Subject [jira] Commented: (CASSANDRA-1154) basic, single node indexing against one indexexpression
Date Thu, 03 Jun 2010 05:59:56 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1154?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12874968#action_12874968

Jonathan Ellis commented on CASSANDRA-1154:
-------------------------------------------

the one part of this sub-task not dealt with in 1153 or a later sub-task is, here I create
index CFs always with BytesType comparator.  This is correct for OPP (technically, BOP) but
we need to support mirroring other key orderings, as column orderings.  In other words, just
as LocalPartitioner uses the value ordering to store index rows on disk in the correct order
(to support operators other than EQ later on), we need to create a PartitonerOrdered[Abstract]Type
that orders columns w/in an index row (that is, columns whose name is a row key) by the same
order those row keys are ordered on disk.  This allows the optimizations mentioned in CASSANDRA-1156.
